Reports of a man recklessly driving a pickup truck with no headlights on led police to Nipmuc Liquors in Webster, where, they said, Mr. Cahill was found slumped over the steering wheel.

Police said Mr. Cahill had a blood-alcohol reading of .311 percent, almost four times the .08 legal limit.

In Dudley District Court, Judge Timothy M. Bibaud recently dismissed the charge of negligent driving, dropped the lights violation charge and continued without a finding the drunken driving charge until Jan. 14, 2014.
